Whereas other builders have saved money by switching to unbranded tubesets from Taiwan, Santana continues to work with Easton to draw superior tandem specific tubes.

• Our custom-drawn 20/10/20 thinwall double-butted 7000-series Santana/Easton aluminum tubing is half the weight, 55% stronger and transmits 60% less road shock than 25/25/25 plain-gauge 6000-series tubing found on other aluminum tandems.
• 35mm top- and lateral- and seat-tubes
• Conical 44–54mm down tube
• 65x35mm ultrawide oval bottom tube
• Comfortable quad-butted seat stays strengthen the brake boss weld zone
• 43x26mm oversize unindented chainstays
• While other aluminum tandem frames deliver an uncomfortable ride and weigh-in at 10 pounds (heavier than our steel frames), Santana’s aluminum frames weigh just over 7 pounds.
